D U S T- BA G SPECIFICATION forming part of Letters Patent No. 569,830,dated October 20, 1896.

Application filed February 27,1896. Serial No. 581,041. No model.)

To all whom it may concern:

Be it known that 1, DAVID HUNT, of Boston, county of Suifolkfita'te ofMassachusetts, have invented an Improvement in Dust-Bags, of which thefollowing description, in con; nection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

In another application, filed by me Septemher t, 1895, Serial No.561,431, a supportingframe with an attached handle is shown adapted tobe used as the supporting-frame of a dust-bag, it being constructed andarranged in such manner that a flexible bag may be connected with it.This frame comprises, essentially, a top portion and two side portions,the handle being connected wit-h the top portion at or near the middle,and when the frame is used as a supporting-frame for a dust-bag thelower ends of the side portions are connected by a strip which serves asa lip over which the dirt is swept, and the flexible bag will beattached to the frame and to this connected strip. Owing toirregularities of floors, &c.,itis frequently very diiiicult to collectthe dirt, and it is the object of this invention to so construct thedust-bag that the lip or edge over which the dirt is swept may be madeto conform to the irregularities in the floors, &c. 5 and to this endthe invention consists in making the supporting-frame elastic orextensible and combining with it a flexible lip or edge strip which maybe drawn and held taut by said elastic or extensible frame, and thusmade to conform to the irregularities by pressure upon the frame, such,for instance, as may be applied to the handle. Such a flexible lip oredge strip may be made of canvas or other material having along itsfront edge a metallic lip or binding, and said flexible strip may beconnected with the ends of the elastic supporting-frame, to be drawn andheld taut by extending said frame by pressure on the handle.

Figure 1 shows in front elevation a dustbag embodying this invention;Fig. 2, a side elevation of the dust-bag shown in Fig. 1; Fig. 3, aperspective view of a portion of the frame and flexible edge strip orlip applied thereto; Fig. 4:, a cross-section of the flexible edge stripor lip taken on the dotted line a: w, and Fig. 5 a cross-section of oneof the blocks forming a part of the elastic supportingframe.

The elastic supporting frame is herein shown as made of wire and bent tocomprise a top portion a and two side portions a CF, each composed ofparallel wires, and the handle is attached to the middle of the topportion. Between the wires of the top and side portions suitable blocks0, of wood or other material, are placed, they being formed with sidegrooves or otherwise formed to receive the wires, and being alsopreferably formed with a concaved recess upon the outer side. There maybe as many of these blocks as desired and they may be disposed in anydesirable way. A canvas or other flexible strip d, herein shown as abelt, is passed entirely around the supporting-frame thus formed, beingheld particularly by the blocks, and this strip cl along the front edgethereof between the lower ends of the side portions of the frame hasattached to it a metal lip d, which may be applied as a binding. If thismetal strip or binding is made of tin or brass it will be more or lessflexible. This lip or binding may be made in many different ways andapplied to the flexible strip in many different ways, all coming withinthe spirit and scope of my invention.

The side portions a a? of the supportingfraine project outwardly fromthe top portion, the space between them gradually increasing towardtheir lower ends, and when the support-ing-frame is resting on the floorand pressure applied upon the handle the lower ends of these sideportions a a will separate and draw the belt or strip (1 between themtaut, as shown by dotted lines, Fig. l, and the flexible strip will thenconform to the irregularities of the floor. The concaved formations inthe blocks give to the flexible strip cl a corresponding transversecurvature, which, when drawn taut, throws the metallic edge (1 downward,as shown in Fig. 4.

The flexible bag 6 is or may be attached to the canvas strip (1 or tothe frame in any desirable way, and, furthermore, a metallic or other 4pan may be hinged or otherwise attached to the rear edge of the strip orto the frame.

I do not desire to limit my invention to the particular way herein shownof constructing or of attaching the strip to the frame, as my inventionbroadly comprehends the combination of a flexible strip and an elasticor extensible frame.

While that portion of the belt between the lower ends of the sideportions a, a which carries the metallic edge may be made of canvas,leather, or other flexible material, the remaining portion of the beltinclosing the frame may consist of wire or of any lacing material.

I claim- 1. The dust-bag or dust-pan herein described, having anextensible supportingframe and a flexible lip or edge strip connectedthereto, and adapted to be drawn and held taut by extending saidsupporting-frame, substantially as described.

2. The dust-bag or dust-pan herein described, having an elasticsupporting-frame, and a flexible lip or edge strip connected thereto,andcurved longitudinally,and adapted to be straightened out by extendingsaid frame, substantially as described.

3. The elastic supporting-frame comprising a top portion and twoout\vardly-pro 'ect i'ng side portions, a handle attached to the topportion, and a flexible lip or edge strip connected with said frame andadapted to be drawn and held taut between the lower ends of the sideportions by pressure upon the frame, substantially as described.

4. The extensible supporting-frame, comprising a top portion and twooutwardly-projecting side portions a, a ahandle attached to the topportion, and a flexible lip or edge strip consisting of a metallic edge,and a belt to which it is applied, said strip being supported upon saidframe and adapted to be drawn to conform to irregularities by pressureupon the frame, substantially as described.

5. The extensible supporting-frame, comprising a top portion and twooutwardly-projecting side portions a, a a handle attached to the topportion, and a belt encircling the frame, and having a metallic edgebetween the lower ends of the side portions, and a flexible bag attachedto said belt, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

D AVID HUNT.
